In addition to the above, the storage unit may be provided with another storage unit such as a spanner or nipper. The storage partition walls 121 to 127 are formed integrally with the storage side case 1 by injection molding, and protrude from the inner surface of the storage side case. Corresponding to the storage partition walls 121 to 127 of the storage case 1, the storage partition walls 121 a to 127 a protrude from the inner surface of the lid case 2 (see FIGS. 2 and 3).

  The upper and lower storage partition walls 121 to 127 and 121a to 127a extend so as to be opposed to each other, and there are long ones that are close to each other and short ones that are not. For example, the corresponding partition wall portions 122a and 124a of the lid case extend close to the partition wall portions 122 and 124 forming the double wall shown in FIG. 2, and are made of an elastic material such as a belt-like rubber. 26, the space closed by the storage side case 1 and the lid side case 2 is divided into a sound path space 1e and a sound path space 1f, which will be described later. The so-called both partition wall portions 121a and 124a function as a room partition wall portion. On the other hand, as shown in FIG. 3, the storage partition walls 121 and 122 extend so as to be spaced apart from the corresponding partition walls 121 a and 122 a of the lid side case, and a gap ( Window) 35a. The gap 35a is provided to form a sound path, as will be described later.

  A pair of speaker units (hereinafter, “speaker unit” is simply referred to as “speaker”) 20 and 21 are attached to the front side wall portion 120 a of the storage case 1. The speakers 20 and 21 are configured by a generally used dynamic cone type. For example, speaker cone papers 20a and 21a having a diameter of about 10 cm and magnets 20b and 21b for driving a voice coil (not shown) are provided. Contains.

  The rear of the pair of speakers 20 and 21 is covered with a speaker cover 34, respectively. This prohibits intrusion of iron chips, dust, or rainwater that may adhere to the speaker magnets 20b and 21b or the cone papers 20a and 21a from the contaminated environment at the work site from the rear of the speaker. That is, as shown in FIG. 3, a speaker cover 34, which is a member for hiding the speaker from the outside, is provided between the right sound path space 1e and the right speaker 20. A hole 34 a is formed in a part of the speaker cover 34. The mesh cloth 30 made in a net shape is stuck and fixed in the hole 34a. The double room partition wall portions 121 and 122 in this portion are provided at a height that is approximately half of the overall height of the tool storage case 120. In this case, the room partition walls 121 and 122 of the storage case 1 are not in close contact with the double partition walls 121a and 122a of the lid case 2 and form a gap 35a of 30 to 50 mm serving as a sound path. The gap 35a and the hole 34a are shifted from each other as a positional relationship in the thickness direction of the tool storage case 120, and form a maze structure. The speaker 21 is configured similarly. The vibration of the cone paper 20a of the speaker 20 reaches the sound path space 1e like the sound flow 40 in the maze sound path 1p. On the other hand, the cordless driver 27 (or the charger 4) placed in the sound path space 1e. ) Are separated and held by the maze and the walls 121, 122, 124, etc., so that the speaker is protected from a tool crash. Further, the chips adhering to the tool and the like are also prevented from entering the speaker magnet and cone paper because of the mesh cloth 30. Further, the sound emitted from the back surface of the cone paper 20a (or 21a) reaches the sound path space 1e through the maze sound path 1p of the hole 34a and the gap 35a like the sound flow 40, and resonates in the sound path space 1e. Efficient and high-quality sound is reproduced.

  The sound path space 1e and the sound path space 1f described above are provided behind each of the speakers 20 and 21 in order to resonate the sound from the speakers, increase the volume, and reproduce the low sound. First, as shown in FIG. 3, a double room partition wall portion (speaker partition wall portion) is provided behind the right speaker 20 arranged in the speaker storage portion 131 in order to partition the storage portion 135 of the tool body 27. ) 121 (121a) and 122 (122a) are provided. The room partition wall is provided with a gap (window) 35a, and the storage part 131 of the speaker 20 communicates with the storage part 135 of the tool body through the gap 35a to form one sound path space 1f. ing. Similarly, the rear side of the left speaker 21 arranged in the speaker storage part 132 communicates with the charger storage part 134 and the battery storage part 136 through the gap (window part) 35b of the room partition wall part to form the sound path space 1e. is doing. In other words, the sound path space 1f communicates with the right speaker 20, and the sound path space 1e communicates with the left speaker 21, and both of the sound path spaces 1f and 1e are double rooms as described above. It is separated or shielded by the partition walls (122 and 124, 121 and 124) and provided independently. In particular, as described above, the double partition wall portions 122 and 124 are covered with the belt-shaped rubber packing 26, and when the lid side case 2 is closed, the double partition wall portions 122a and 124a of the lid side case 2 are closed. Since the belt-like rubber packing 26 is configured to have a dimensional relationship that can be crushed by an appropriate pressing force, the left sound path space 1e and the right sound path space 1f are more completely separated, and stereo sound is more completely separated, resulting in high sound quality Can be played. Further, chatter noise in a slight gap is absorbed by the rubber-like elastic material and can be prevented. It is more effective if glass wool is packed between the double partition walls.

  Thus, according to the present invention, the storage case 1 and the lid case 2 function as speaker enclosures for the pair of speakers 20 and 21 in a state where both are closed by the latch 37. The sound path space of a commercially available speaker enclosure has many cubic shapes. However, according to the present invention, the cordless driver drill 27, the charger 4 or the battery pack (cassette type storage battery) 5 is efficiently saved in the sound path space. With the deformed shape that can be accommodated in the case, it is possible to obtain the same effect as the conventional one.

  Therefore, according to the present invention, the tool storage case 120 accommodates the tool main body 27, the charger 4, and the battery pack 5 in the sound path spaces 1e and 1f during transportation, so that the sound device 16 described later. In addition, the tool body 27 is easily carried as one package (luggage). Thereby, the conveyance efficiency can be improved. Further, when the audio device 16 described later is used, if the tool body 27 and the other electric devices 4 and 5 are used in a state where they are taken out from the tool storage case 120, the speakers (20, 21) having a fine sound path space. It becomes a high-quality sound device with attached. Of course, this can be put to practical use even if a stored item such as a tool body is put in the tool storage case, although there is a slight deterioration in sound quality due to a decrease in sound volume.

  Covering the front of the pair of speakers 20 and 21, a dust shielding filter 32 made of a non-woven fabric made of a chemical fiber or a thin plastic material is detachably disposed, and a resin mesh (lattice) or slit is formed thereon. A grid cover (attachment tool) 33 is detachably fitted to the side wall 120a and fixed. The grid cover may be fixed to the side wall 120a by screwing. The dust blocking filter 32 is for preventing dust, iron powder, or rainwater unique to the construction site from adhering to the cone papers 20a and 21a of the speakers 20 and 21 and damaging them. In particular, even if iron chips generated during work at the work site are attracted and adhered to the speaker magnets 20b and 21b, they can be removed by removing the grid cover 33 from the side wall 120a and replacing the dust blocking filter 32. is there. Since the grid cover 33 has a coarse mesh or a lattice shape, it does not hinder sound.

In addition, each circuit unit of the audio device 16 may be provided with a circuit board built-in portion in the storage case 1 and a part of the storage case 1 may be configured as a casing. Other electrical devices 15 and 8 can also be constructed using circuit components formed by well-known integrated circuit technology. The MD player 8 may be a commercially available one.

  In the embodiment shown in FIG. 1, a commercially available MD player 6 is installed in the storage part 134 a of the case 1 and fixed by the fixing band 7. By using a stretchable rubber band as the fixing band 7, it becomes possible to fix a commercially available MD player having various sizes, and the MD player is fixed in a case so as not to move. It can also be played inside. Instead of the rubber band, a length adjustable cloth belt may be used.

  The MD player 6 is electrically connected to the jack 9 via the detachable signal line 8 and further electrically connected to the audio amplifier circuit 108 via an internal wiring 28 described later. With this connection, audio is reproduced by the audio amplifier circuit 108 and the speakers 20 and 21.

  As shown in FIG. 4, the display circuit 109 of the audio device 16 is electrically connected to a liquid crystal display 29 that is disposed so as to be exposed on the outer surface of the front side wall 120 a of the storage case 1, and drives and displays the liquid crystal display 29. . The liquid crystal display 29 displays mode switching information, reception frequency information of the radio tuner 103, clock time information, and the like.

  The GPS unit 15 can display position information on the liquid crystal display 29. The position information by the GPS unit 15 eliminates the need for a map for going to an unguided work site, and also prevents the tool body from being stolen. As shown in FIG. 1, the GPS unit 15 is housed in a GPS housing portion 137, and, as will be described later, the liquid crystal display of the audio device 16 by the wiring 28 disposed between the double room partition walls 122 and 124. 29 is electrically connected.

The switches (104 to 107) are not limited to the push type, and even a known rotary switch can be protected against dust and water when used in combination with waterproof means such as an O-ring.

  Further, the switches 18 (104 to 107) or the liquid crystal display 29 of the display unit are in a positional relationship in which the storage side case 1 and the lid side case 2 or the front surfaces of the speakers 20 and 21 are recessed by 10 mm or more. As a result, when an obstacle such as wood collides during transportation at a work site, it is as difficult as possible to hit the switches and the display unit, and is protected from damage.

[Configuration of power supply and power supply wiring]
As shown in FIG. 5, the power source of the audio device 16 is a commercial AC power source or other AC power source (AC) such as a generator supplied through a plug 10, a power cord 11, and an internal wiring 28, which will be described later. The DC power supply of the AC-DC converter power supply circuit 101 to be converted into the power supply circuit 101 is used, or the DC power supply of the spare battery pack (cassette type storage battery) 5 stored in the battery storage unit 136 is used. Both power sources are fed to the power source switching circuit 102 by the internal wiring 28 installed in the storage case 1 and are selectively selected by the power source switching circuit 102 so that one of the voltages is applied to the audio device 16. Used as an operating power source for the circuit units 103, 108, and 109. Further, this power source may be used as an operating power source for the MD player 6 and the GPS unit 15. In the example shown in FIG. 5, if the plug 10 is connected to an AC power supply, the AC-DC converter power supply circuit 101 outputs a DC voltage to the line 28 and the relay switch 102a of the power supply switching circuit 102 is connected to the battery pack 5. Is automatically switched from the side to the AC power source AC side, and the battery pack side power source is automatically switched to the AC side power source. This automatic switching circuit 102 is advantageous when the power consumption of the battery pack 5 is reduced or when the AC power source is used for a long time.

  The spare battery pack (cassette type storage battery) 5 for supplying DC power has the same outer shape and charge / discharge capacity as the battery pack (cassette type storage battery) 3 set in the tool body (cordless driver drill) 27. used. For example, it is comprised from a nickel cadmium battery (Nicad battery) or a nickel metal hydride battery of 7.2V to 24V. The cassette type storage battery 5 is set or fixed to a storage part 136 partitioned by a single storage partition wall part 123 and a double storage partition wall part 124. The engagement mechanism between the battery pack storage portion 136 of the storage case and the battery pack 5 is the same mechanism as the engagement mechanism between the battery pack 3 and the tool body (cordless driver drill) 27.

  The engagement mechanism for fixing the battery pack 5 to the storage portion 136 is shown in the sectional view of FIG. That is, a battery bracket (mounting tool) 36 is fixed to the storage case 1, and the bracket 36 includes a battery insertion hole 36 a into which the insertion portion 5 c having a substantially elliptical cross-sectional shape of the battery pack 5 is inserted, and a battery pack. 5 has a latch receiving portion 36b that engages with a claw portion (hook portion) 5b of the latch 5a. The wiring terminals 23 and 24 are in electrical contact with the positive electrode and the negative electrode exposed on the opposing outer peripheral surfaces of the elliptical insertion portion 5c of the battery 5 by the elastic force of the terminal itself. The battery voltage is supplied from the pair of terminals 23 and 24 to the automatic power supply switching circuit 104 shown in FIG. Such an engagement mechanism of the bracket 36 has the same structure as the engagement mechanism of the battery pack 3 used for the tool body 27 and the tool body (cordless driver drill) 27.

  As described above, the spare battery pack 5 can supply power to the tool storage case 120 by the latch mechanism provided in the battery storage portion of the storage case 1, so During transportation, it is possible to listen to an audio device such as a radio by using the battery pack as a power source. At this time, since the battery is fixed by the latch mechanism, it is possible to prevent the battery from falling off and to prevent the battery from being poorly contacted due to vibration. Note that the above-described latch mechanism can easily hold the spare battery pack 5 by providing an elastic body or a rib inside the lid-side case 2 facing the spare battery pack 5.

  On the other hand, as shown in FIG. 1, the AC power is taken into the tool storage case 1 by the plug 10 and the power cord 11 and converted into a DC low voltage by the AC-DC converter power supply circuit 101 described above. Supplied to audio device, GPS unit, etc. As shown in FIG. 1, a plug 10 for taking in AC power is housed in a plug housing part 139 in a case that is partially opened to the outside of the tool housing case 1, and is electrically connected to the plug 10. The connected power cord 11 is stored in a cord storage portion 138 provided adjacent to the plug storage portion 139. The power cord 11 employs a well-known automatic winding structure. In other words, the bobbin 13 is wound around the bobbin 13, and the bobbin 13 has a structure in which the power cord is automatically wound by the rotation of the bobbin by the claw spring 12. When the AC power source is not used, the plaque 10 is stored in the plug storage portion 139. When the AC power source is used, the power cord 11 can be extended to about 2 m by pulling out the plaque 10. By adopting a lock mechanism in a known automatic winding structure, it is possible to fix the extension length.

  As described above, the AC power cord 11 drawn out from the tool storage case 120 is automatically wound so that unnecessary power cords do not come out of the storage case during transportation of the tool storage case. It can prevent the equipment from being crushed or damaged.

  As shown in FIG. 1, the storage case 1 is provided with an outlet 11 a for directly supplying power to an electric device with AC power supplied to the plug 10. For example, when it is desired to supply AC power to the plug 4 a of the charger 4, the AC power can be supplied to the charger 4 by inserting the plug 4 a into the outlet 11 a near the storage portion of the plug 4 a. In this case, without removing the charger 4 from the tool storage case 120 to the outside, the battery pack to be charged is inserted into the battery insertion portion (hole) 4b of the charger 4 and fixed by a latch mechanism (not shown). It can be used in the tool storage case 120. Thereby, the battery pack is charged while preventing the dirt of the charger 4 due to dust such as iron chips at the work site, in particular the dirt of the terminal (not shown) of the bracket of the battery insertion portion 4b by the lid side case 2. be able to.

[Configuration of internal wiring]
The internal wiring including the power supply wiring in the tool storage case 120 is disposed along the storage partition wall portion or the room partition wall portion (122, 124, etc.) provided in the storage side case 1. For example, the internal wiring 28 of the power source extending from the end of the power cord 11 accommodated in the cord accommodating portion 138 to the AC-DC converter power supply circuit 101 of the audio device accommodating portion 133 is connected to the left sound space 1e and the right sound. It arrange | positions between a pair of room partition wall parts 122 and 124 which comprise a double wall part between the way space 1f. As described above, the double room partition walls 122 and 124 are integrally formed in a rib shape with the case body by injection molding, and the room partition walls 122 and 124 are juxtaposed with each other at an interval of about 10 mm. In the space between the pair of room partition walls juxtaposed at intervals of about 10 mm, terminals 23 and 24 of the bracket 36 to which the above-described spare battery pack 5 is latched and fixed, including the internal wiring 28 of the AC power source (see FIG. 2), the internal wiring 28 of the MD player 6 stored in the storage unit 134a, the internal wiring 28 of the GPS unit 15 stored in the storage unit 137, and the like. Further, as described above and shown in FIG. 2, the double partition wall portions 122 and 124 are covered with the belt-shaped rubber packing 26, and when the lid side case 2 is closed, 2 of the lid side case 2. There is a dimensional relationship in which the belt-like rubber packing 26 is crushed by an appropriate pressing force at the heavy partition wall portions 122a and 124a.

  In this way, the internal wiring of the power supply and other signal internal wiring are arranged between the double room partition wall or the storage partition wall and covered with the belt-shaped rubber packing 26, so that the storage tool or the like can be used as a sound path. It is possible to prevent the internal wiring from being damaged or disconnected without damaging the internal wiring when taking it into and out of the space (storage portion). Further, as described above, since the belt-like rubber packing 26 is crushed between the lid side case 2 and the storage side case 1, the sound path space is sealed and the internal wiring 28 does not affect the sound separation. .

  As shown in FIG. 1 and FIG. 2, between the double room partition wall portions 121 and 122 extending in the horizontal linear direction and between the double room partition wall portions 121 and 124, a copper wire (wire) such as the feeder described above is provided. Shape) or a metal rod (rod shape) FM antenna 22 is housed. The FM antenna 22 has a length of about 45 cm, for example. On the other hand, the AM bar antenna 17 is composed of, for example, a ferrite rod and a coil having a length of 10 to 20 cm, and is built in the body of the unit 16 of the audio device housed in the audio device housing part 133. In this way, by utilizing the wide space of the tool storage case 120 and incorporating the antenna, it is possible to prevent the occurrence of damage such as a collision with objects during transportation or work. Moreover, since the internal space of the tool storage case is wide, the directivity of the antenna can be reduced if the tool storage case is arranged not only in a straight line but also in an L shape.

[Modification of speaker enclosure]
6 to 10 are configuration diagrams showing other embodiments of the present invention. In particular, FIG. 6 is a configuration diagram showing a modification of the speaker enclosure.

  The speaker enclosure shown in FIG. 1 has a structure in which the left and right sound path spaces 1e and 1f provided behind the speakers 20 and 21 are sealed, and is similar to what is generally known by the name of “sealed speaker”.

Of course, this duct space 1s is provided continuously not only in the storage case 1 but also in the opposing portions 2s (not shown) of the lid case 2. Therefore, the rib-shaped duct wall 1t of the storage-side case 1 is also continuous with the corresponding rib-shaped duct wall 2t (not shown) of the lid-side case 2. The volumes of the duct spaces 1s and 2s defined by the rib-shaped duct walls 1t and 2t are determined in consideration of speaker characteristics and sound volume, according to the frequency of the bass to be reproduced. The duct opening 1u at the exit of the sound path (the cover side case 2 also has a corresponding opening 2u) is designed in the same manner. According to such a bass reflex type speaker enclosure, richer powerful bass can be reproduced.

  In addition, the duct wall 1t provided in the storage-side case 1 can be used as a partition wall that partitions the storage. In this modification, the duct wall 1t provided in the right sound path space 1f is Further, the handle portion 27a of the cordless driver drill 27 can also be pressed (locked), and rattling of stored items can be prevented. Further, since the duct wall 1t is formed of a thin rib, it can be easily elastically deformed and can protect the case itself and the main body from an impact such as dropping.

  Further, a duct mesh 39 is fixed to the entrance of the duct space 1s (2s) by a known fixing method such as adhesion or pinching. Thereby, invasion of dust into the duct spaces 1s and 2s and loss of small articles stored in the case to the outside are prevented.

  Unlike the example shown in FIG. 1, the power cord 11 accommodated in the cord accommodating portion 138 of the accommodating case 1 is not attached to the winding mechanism. It is simply folded and stored in the storage unit 138. Even if the long power cord 11 is pushed in here, it can be transported.
